Title
Berge-Fulkerson coloring for C(8)-linked graphs.
Abstract
It is conjectured by Berge and Fulkerson that every bridgeless cubic graph has six perfect matchings such that each edge is contained in exactly two of them. Let G be a cubic graph and F={C1,...,Cr} be a 2-factor of G such that |Cj| is odd if and only if j2k for some integer k. The 2-factor F is C-(8)-linkedif, for every ik, there is a circuit Di of length 8 with edge sequence e1ii). And the cubic graph G is C-(8)-linked if it contains a C-(8)-linked 2-factor. It is proved in this article that everyC((8))-linked cubic graph is Berge-Fulkerson colorable. It is also noticed that many classical families of snarks (including some high oddness snarks) are C-(8)-linked. Consequently, the Berge-Fulkerson conjecture is verified for these infinite families of snarks.
